Abstract
The synthesis of a water-insoluble metal ion complexing resin was carr ied out by radical polymerization of 2,2-bis(acrylamido) acetic acid. The resin was characterized by elemental analyses, FTIR spectroscopy, and thermal analyses. The ability to bind copper(II), iron(II), iron(I II), and uranium(VI) as well as the elution of the metal ions from the loaded resins were studied. For uranyl ions, pH 5 was the optimum sor ption pH value. Sorption selectivity from the binary mixture Cu(II) U(VI) was studied at pH 2. The thermal stability is increased by adsor ption of UO22+. According to these results a coordination mechanism is suggested for sorption of copper and uranium. (C) 1995 John Wiley & S ons, Inc.
